Quick Comparison

Quick answer

The best dehydrated dog food for dogs with bad breath is Merrick Backcountry Raw Infused Dehydrated Dog Food because it combines high protein with natural ingredients that promote dental health. For dogs with sensitive stomachs, Wellness CORE RawRev Dehydrated is a close runner-up. Our picks focus on formulas that minimize odor-causing bacteria through better digestion and quality ingredients.

What to consider for Dehydrated Dog Food For Dogs With Bad Breath

Bad breath in dogs often stems from dental plaque, gum disease, or digestive issues. Dehydrated dog food can help by being less processed and more digestible, reducing the food particles that feed bacteria. Look for recipes with named meat proteins, limited fillers, and added probiotics or digestive enzymes. Avoid artificial preservatives and high-carb fillers that can ferment and cause odor. Always consult your veterinarian to rule out underlying health problems.

What to look for in a dog food

Choose a dehydrated dog food that is AAFCO complete and balanced for your dog’s life stage (adult, puppy, or senior). The first ingredient should be a named meat source like chicken, beef, or salmon. Protein content should be between 25 to 35% on a dry matter basis, fat around 12 to 20%, and calories appropriate for your dog’s activity level. For large breeds, ensure calcium and phosphorus levels are suitable. Omega-3 fatty acids from fish oil or flaxseed can support skin and coat health, while joint supplements like glucosamine and chondroitin may help older dogs. Avoid recipes with unnamed meat meals or excessive legumes.

How we chose these picks

  • Evaluated ingredient lists for named meat proteins and absence of artificial additives.
  • Checked AAFCO nutritional adequacy statements for the appropriate life stage.
  • Compared protein, fat, and fiber content to ensure balanced nutrition.
  • Reviewed customer feedback for palatability and digestive tolerance.
  • Prioritized brands with a history of quality control and safety recalls.
  • Considered added dental health benefits like kibble texture or ingredients that reduce plaque.
  • Consulted veterinary nutrition guidelines for general recommendations.
  • Never ranked a product higher just because it pays a commission.

What to avoid

  • Unnamed “meat meal” as the primary protein source; opt for named meats like chicken meal or salmon meal.
  • Grain-free or legume-heavy recipes unless your veterinarian specifically advises them, due to the ongoing FDA investigation into a potential link with canine dilated cardiomyopathy (DCM).
  • All-life-stages food for large-breed puppies, as it may have improper calcium levels.
  • Abrupt diet switches; transition over 7 to 10 days to avoid digestive upset.

Top 5 Picks

#1
Merrick Backcountry Raw Infused Dehydrated Dog Food, Grain-Free Chicken & Sweet Potato Recipe
Best Overall

Merrick Backcountry Raw Infused Dehydrated Dog Food, Grain-Free Chicken & Sweet Potato Recipe

View on Amazon

This formula features deboned chicken as the first ingredient, providing high-quality protein that supports lean muscle and digestion. The freeze-raw infused pieces add flavor and texture that dogs love. It includes probiotics for digestive health, which can help reduce bad breath. However, it is grain-free, so consult your vet before feeding if your dog has no grain sensitivity.

#2
Wellness CORE RawRev Dehydrated Dog Food, Grain-Free Turkey & Duck Recipe
Best for Sensitive Stomach

View on Amazon

Wellness CORE RawRev uses turkey and duck as novel proteins, which can be easier on sensitive stomachs. The dehydrated pieces are mixed with kibble for a crunchy texture that may help scrape plaque.

#3
Blue Buffalo Wilderness Dehydrated Dog Food, Chicken Recipe
Best Budget

Blue Buffalo Wilderness Dehydrated Dog Food, Chicken Recipe

View on Amazon

Blue Buffalo Wilderness offers a more affordable dehydrated option with real chicken and wholesome grains like brown rice. It includes LifeSource Bits for antioxidants. The crunchy texture can aid in reducing tartar buildup. However, it contains more carbohydrates than some other options, which may not be ideal for all dogs.

#4
Purina Pro Plan Dehydrated Dog Food, Chicken & Rice Formula
Best for Puppies

Purina Pro Plan Dehydrated Dog Food, Chicken & Rice Formula

View on Amazon

This formula is specifically designed for puppies, with DHA for brain development and calcium for strong bones. It uses chicken as the first ingredient and includes rice for easy digestion.

#5
Diamond Naturals Dehydrated Dog Food, Lamb Meal & Rice Formula
Best Grain-Inclusive

Diamond Naturals Dehydrated Dog Food, Lamb Meal & Rice Formula

View on Amazon

Diamond Naturals features lamb meal as the primary protein, which is a novel option for dogs with food sensitivities.

One limitation is that it contains lamb meal rather than fresh lamb, but it is still a high-quality ingredient.

Before You Buy

Key Buying Factors

01

Protein Source

Look for a named meat protein as the first ingredient. Novel proteins like turkey, duck, or lamb can be helpful for dogs with food sensitivities that may contribute to bad breath.

02

Digestive Health

Probiotics, prebiotics, and digestive enzymes aid in breaking down food thoroughly, reducing fermentation and odor. Formulas with added fiber like pumpkin or beet pulp can also help.

03

Kibble Texture

Crunchy dehydrated pieces can mechanically scrape plaque and tartar from teeth, similar to dental chews. Larger kibble sizes may encourage chewing, which promotes saliva production and oral health.

04

Ingredient Quality

Avoid artificial preservatives, colors, and flavors. Natural preservatives like mixed tocopherols are preferable. High-quality ingredients are more digestible and less likely to cause bad breath.

05

Life Stage Appropriateness

Ensure the food is formulated for your dog's life stage. Puppy, adult, and senior formulas have different nutrient profiles to support growth, maintenance, or aging needs.

Living With It

Care, Cost and Maintenance

Proper Rehydration

Follow package instructions for adding water. Use warm (not hot) water to preserve nutrients. Let the food sit for 5 to 10 minutes until fully rehydrated. Stir well before serving to ensure even moisture.

Storage Guidelines

Store dehydrated food in a cool, dry place. Once opened, seal the bag tightly or transfer to an airtight container. Use within the manufacturer's recommended time frame, usually 30 to 45 days, to maintain freshness and prevent spoilage.

Transitioning Diet

Gradually mix the new dehydrated food with your dog's current food over 7 to 10 days. Start with 25% new food and 75% old, then increase by 25% every few days. Monitor for digestive upset and adjust the pace if needed.

Pro tip

Add a spoonful of plain canned pumpkin to your dog's meal: the fiber helps digestion and can further reduce bad breath.

Frequently asked questions

How much dehydrated dog food should I feed my dog?
Feeding amounts vary by brand, but generally, dehydrated food expands when rehydrated. Start with the manufacturer's recommendation based on your dog's weight. For example, a 30-pound dog may need about 2 to 3 cups of rehydrated food per day, split into two meals. Adjust based on activity level and body condition. Always provide fresh water.
How many calories are in dehydrated dog food?
Calorie content varies, but most dehydrated dog foods range from 360 to 420 kcal per cup as fed (rehydrated). Check the label for exact numbers. Because dehydrated food is more nutrient-dense, you may feed less volume compared to traditional kibble. Use a kitchen scale for accuracy if needed.
Is grain-free dehydrated dog food safe?
Grain-free diets have been linked to a potential risk of dilated cardiomyopathy (DCM) in some dogs, according to an ongoing FDA investigation. While not all grain-free foods cause issues, they often contain legumes or potatoes as substitutes, which may be problematic. Unless your veterinarian recommends grain-free for a specific allergy, grain-inclusive formulas are generally considered safer.
Can I feed dehydrated dog food to my puppy?
Yes, but ensure the formula is labeled for puppies or all life stages and meets AAFCO puppy nutrient profiles. Puppies need higher protein, fat, and calcium for growth. Avoid large-breed puppy formulas that are all-life-stages, as calcium levels may be too high. Always consult your vet for specific recommendations.
Is dehydrated dog food good for overweight dogs?
Dehydrated food can be part of a weight management plan because it is often higher in protein and lower in carbohydrates. However, portion control is key. Look for formulas with lower fat content (around 10 to 12%) and higher fiber. Measure servings carefully and reduce treats. Consult your vet for a tailored weight loss program.
Is dehydrated dog food suitable for senior dogs?
Yes, many senior dogs benefit from dehydrated food because it is easy to digest and can be rehydrated to a softer texture for dogs with dental issues. Look for formulas with added joint support like glucosamine and chondroitin, and moderate protein to support muscle mass without overloading kidneys. Always check with your vet.
Can I feed dehydrated dog food to small or large breeds?
Yes, but choose a formula appropriate for your dog's size. Small breeds may need smaller kibble or pieces to prevent choking. Large breeds require balanced calcium and phosphorus levels to support bone health. Some brands offer breed-specific formulas. Always follow feeding guidelines and monitor your dog's weight.
Is dehydrated dog food better than dry kibble for bad breath?
Dehydrated food can be beneficial because it often contains higher quality, more digestible ingredients that reduce fermentation in the gut, a common cause of bad breath. The crunchy texture also helps mechanically clean teeth. However, it is not a substitute for regular dental care like brushing or professional cleanings.
Can dehydrated dog food help with dental disease?
The crunchy texture of dehydrated kibble can help scrape plaque and tartar from teeth, similar to dental chews. However, it is not a cure for existing dental disease. For dogs with periodontal issues, a soft or rehydrated diet may be more comfortable. Always have your vet evaluate your dog's oral health and recommend appropriate treatments.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
